Description

Ilium bone taking device

Technical Field

The utility model relates to the technical field of medical appliances, in particular to an ilium bone taking device.

Background

Bone particles are usually obtained by an ilium bone extraction operation prior to bone grafting, and the ilium bone extraction operation is usually carried out by several surgeons cooperatively using an ilium bone extraction device to extract bone from a patient. As shown in figure 3, the existing bone extractor comprises a limiting cylinder, a handle and a bone extraction rod; when the bone taking rod is used for smashing ilium from the limiting cylinder, the acting force pushing the limiting cylinder can be generated when the limiting cylinder is pressed on ilium, so that the limiting cylinder is easy to shift, and the ilium bone taking operation is difficult to accurately and rapidly complete. As can be seen from fig. 3, the limiting cylinder is not provided with a corresponding fixing structure or holding structure for fixing on bones, when in use, other doctors are required to apply acting force to the limiting cylinder through the handle, the other doctors smash ilium with the bone taking rod, more than two doctors are mutually matched, and in the tension environment of operation, the acting force applied to the limiting cylinder by the doctors through the handle is easy to deviate, so that the limiting cylinder is displaced, and the bone taking is inconvenient. When taking bones, in order to relieve the tension of doctors, the operations are occasionally stopped at intervals so as to facilitate the doctors to rest slightly, thereby causing the operations to be performed insufficiently smoothly and with low efficiency.
